Zitat:Dear Christoph,
You will also need to enable the main supply. See paragraph 9.6 in the datasheet.

Also, when using unbalanced source, you need to connect the inverting inputs to ground. Otherwise the connections are correct.

Kind regards,
Jos

Dear Mathijs,

I just bought an UcD32MP amplifier module for the third way/woofer channel (Sub out) of the AS2.100I have a 3-Way System: Tweeter and Mid connected to the AS2.100 and two woofers. One for each channel of the UCD32MP via Sub out of the AS2.100.

How is the best way to connect them?

J1: AC Mains is clear (perhaps directly in parallel to the AC mains of the AS2.100?)

J6: Loudspeaker output is clear (1 speaker for each channel of the UcD32MP)

Supply output (J9):
J9:6 (AMP_EN) connected to J9:4 (GND)

User Application Connector (J2):
AS2.100 Sub out minus connected to J2:9 and J2:11 (Inverting audio input CH1 and CH2)
AS2.100 Sub out plus connected to J2:10 and J2:12 (Non-inverting audio input CH1 and CH2)

Would that be enough/OK? Or do you have some other recommendations?

Best regards,
Christoph
